A vendor sold a combined 234 sodas and hot dogs. The number of sodas was two times the number of hot dogs sold. Find the number

babymother [125]

Answer:

156 hot dogs
78 sodas

Step-by-step explanation:

A group of 2 hot dogs and 1 soda makes a group of 3 items. There were ...

234/3 = 78

groups of items sold.

Since there is 1 soda in the group, that's 78 sodas. The number of hot dogs is 2 times that, or 156 hot dogs.

78 sodas and 156 hot dogs were sold.

At the gym, Jasper was able to bench press 224 pounds, which was 7/8 of the weight that Balin was able to bench press. Which sho

Rzqust [24]

Answer:

The answer SHOULD be 7/8=224/x;256 pounds.

You may have made a mistake in inputting it here on Brainly. So look for the one that matches that.

Step-by-step explanation:

This is what we know:

Jasper = 224 pounds

Balin = x

Jasper = 7/8 of x

Now we make an equation for that:

$(\dfrac{7}{8})(x) = 224pounds$

To match the selections we will isolate 7/8 on one side of the equation:

$\dfrac{7}{8}=\dfrac{224}{x}$

Using ratio and proportion we can solve for what x is. Multiply 224 by 8 and divide it by 7. Or you can do it this way too:

$\dfrac{7}{8}=\dfrac{224}{x}$

$(7)(x)=(224pounds)(8)$

$7x=1792pounds$

$x=\dfrac{1792pounds}{7}=256pounds$

So x = 256 pounds
